I am finding some brownish staining in front of my bed on the drivers side. The stain starts where the structure angles in towards the mattress and goes to the cab-over floor. I've cleaned this area various times and the stain will reappear.

I have driven the camper in pouring rain and nothing happens, I can camp at White Pass ski area for a week and still nothing happens. Yesterday I drove down to Yakima in clear weather and boom the stain reappeared. Just doesn't make sense.

There is no evidence of staining in the ceiling (no moisture either), I have checked all seals, running lights (LED) and I have used Eternabond tape on the front and rear cap seals. I camp full time in the winter and am dumbfounded by this. Any ideas?

Have you moved the matress to see if the stain is isolated? I've heard stories of large amounts of condensation under the matresses due to body heat. Give us a picture of the stain if you can.

Stain is not under mattress, but in nose of the interior. As I stated in my text it starts in the nose and goes down towards the cab-over floor. I'll take a picture next time it happens, I just cleaned the area this morning.

I'm using my Blackberry for internet so posting picture may take some time.

I'm pretty sure that would be a leak around or from the front marker light.
Did you inspect the marker lights for interior moisture?

Rich the marker lights are LED and fully sealed and caulking around each light is good. Puzzling isn't it. When ski season is over I'll try the electric blower and soap, maybe that will show something.

When moisture freezes, it expands right? Seems like even the smallest amount of moisture could shoulder it's way into or through any catch or opening in caulk.
As I've found out, it doesn't matter how good the caulk looks, it can still have a leak.
My money is on the marker lights.

It will not be IN the lights but is getting UNDER them. If you cannot see it then perform a sealtech test or it's equivalent.
That it is not all the way down seems to me to be a very small leak. These can be tough to sort out. IMO it is the light and I would remove and reseal and replace it.

Here is what I found this spring. I was reading this forum and noticed that Rich was having a leak too. Someone suggested that he look at the edges of the Eternabond tape and since I also used Eternabond I decided to do the same.

I had already checked this area, but checked from the roof and not close up from the side since I don't have a step ladder at the ski area (guess I could have gone to the shop). Anyway, once I returned home for the summer I broke out the step ladder and did a thorough inspection and bingo found the leak. It was right at the edge of the Eternabond and not visible looking down from the roof.

The only time water would get in was when Ice would build up in the rain gutters and then start to melt. All fixed now!



1st pic shows the crack and where I removed some Eternabond. 2nd pic is the repair.
